Abstract: In a one-surface coated papermaking belt composed of a base layer and a thick resin layer, or a covered, one--surface coated papermaking belt composed of thin and thick resin layers on opposite sides of a base layer, curling of the edges of the belt due to the shrinkage of the thick resin layer is reduced by forming the opposite side edge parts of the thick resin layer thinner than the middle part. The reduction in curling results in improved oil removal especially in a shoe-press belt. It also stabilizes turning of the belt and facilitates belt installation.

Title: Vehicular transmission
Inventor: UCHIYAMA NAOKI
IPC: F16H57/035

Granted: 2008-07-22
Abstract: An inlet opening 41 for a discharge oil passage 76 is provided in a chamber R1 which accommodates a transmission device comprising a drive pulley 8, a driven pulley 9 and a belt 10. This inlet opening is positioned at a location where the inner wall of the chamber is met by a line drawn tangentially to the pitch circle of the drive pulley whose pitch radius is at a maximum and to that of the driven pulley whose pitch radius is at a minimum. This inlet opening 41 for the discharge oil passage 76 is positioned also at a location where the inner wall is met by a line drawn on the upper side of the pulleys tangent to the peripheries of the drive and driven pulleys 8 and 9. By providing an inlet opening for the discharge oil passage in this arrangement, the lubrication oil which is being thrown from the belt 10 is efficiently discharged through the inlet opening 41 directly to the outside of the chamber. This lubrication oil is then led through the discharge oil passage 76 to the oil pan 26. As a result, while the amount of the oil in the oil pan located below the chamber is maintained at a certain amount, the amount of the lubrication oil which flows down along the inner walls of the chamber is kept to a substantially small amount. In this way, the rotational loss which may be caused from agitation of the oil by the drive pulley is substantially reduced.

Abstract: A method and apparatus for removing drill cuttings from an oil and gas well drilling platform provides for the separation of drill cuttings from at least a volume of the well drilling fluid (i.e. drilling mud) on the drilling platform so that the drilling fluids can be recycled into the well bore. The cuttings are then transferred to a cuttings collection area on the platform. The separated drill cuttings are then suctioned with a first suction line having an intake portion. The suctioned drill cuttings are transmitted to a vacuum holding tank or multiple tanks on the platform, each having a tank interior. A vacuum is formed within the holding tank interior with a blower that is in fluid communication with the tank interior via a second vacuum line. The holding tank is then connected to a floating work boat with a discharge flow line. Cuttings are then transmitted from the tank on the platform to the work boat via the flow line. In an alternate embodiment, cuttings can be transferred to an underwater storage area. In this fashion, multiple holding tanks on the drilling platform can be used to store cuttings until a work boat arrives.    The work boat can be provided with its own high capacity work boat holding tank (for example 100-1000 barrels) for receiving cuttings from the multiple tanks on the drilling platform when disposal is desired. The underwater storage tank can be used in place of or as a supplement to the work boat holding tanks.

Title: Method of providing transfer capability on web-based interactive voice response services
Inventor: MATAGA PETER ANDREW
IPC: H04M3/58
Filed: 2000-03-13
Granted: 2003-04-22
Abstract: Interactive voice response (IVR) services are provided to an end user at a telephone terminal connected to the PSTN through a telephone/IP server that serves as an interface between the PSTN and an IP network such as the Internet. A  first IVR service is provided by a web server running a service logic for that service, which produces pages formatted in a phone markup language (PML) in response to an HTTP request sent over the IP network by the telephone/IP server to the web server at the URL address associated with the service. These pages represent an interactive dialog for that first service, which when received by the telephone/IP server, are translated and converted to audio by an interpreter for audio presentation to the end user. The end users responses, either verbal or touch-tone, to questions posed during the dialog are collected by the telephone/IP server, translated, and forwarded to the web server. Hyperlinks to a second IVR service offered on a web server at a different URL address are embedded and associated with a specific question or statement in a PML-formatted page produced by the first service.  When the end user affirmatively responds to that statement or question through a verbal or touch-tone input, the telephone/IP server translates that response as a "click" on the hyperlink and establishes a virtual connection to the hyperlinked URL address of the web server providing the second service. Further, information associated with the end users interaction with the first service, such as his identity, PIN, and/or zip code, is transferred to the second service by means of a cookie, URL encoding or other information transference mechanism, to provide an audio experience that seamlessly transfers the end user from the first service to the second.

Abstract: An object of the present invention is to provide an antenna feeding circuit, which requires no balance-unbalance converter and has a simplified structure.      The object is attained, by an antenna feeding circuit, according to the present invention, in which micro-strips lines are constituted from one or more pair(s) of band conductors (5a, 5b) disposed on the outer surface of the cylindrical body (1) and an inner conductor (6) disposed on the whole of the inner surface of the cylindrical body (1). A 180 degree distributor (2) supplies electric power to the band conductors (5a, 5b) so that the phase difference between the currents in,the band conductors (5a, 5b) is 180 degrees, and due to this, inutile current generated in accordance with the connection of the balance and unbalance lines.      Inutile current induced in the inner surface of the inner conductor can be cancelled out, because the inner conductor 6 is disposed on the whole of the inner surface of the cylindrical body (1).

Title: Chiral twist laser and filter apparatus and method
Inventor: GENACK AZRIEL ZELIG
IPC: H01S3/105
Filed: 2000-02-04
Granted: 2009-06-09
Abstract: A defect causing a localized state is induced in a chiral structure (12) composed of multiple chiral elements (20, 22) by twisting one element of the chiral structure with respect to the other elements along a common longitudinal axis such that directors of the element molecular layers that are in contact with one another at contact area (26) are disposed at a particular "twist" angle therebetween, the twist angle being greater than a shift angle between directors of consecutive layers. The chiral twist structure may be utilized in a variety of applications such as filters, lasers and detectors. The defect caused by the twist may be made tunable by providing a tuning device for rotating one or more of the chiral elements with respect to one another to vary the twist angle and thus vary the position of the induced defect within a photonic stop band. Tunable defects may be advantageously utilized to construct tunable wavelength chiral filters, detectors and lasers.
